This is the Official Website of Poseidon Linux in English

Poseidon (GNU/)Linux was designed as a friendly and
complete
desktop, based on open source software and aimed at the international
scientific
community (students, technicians, professors, researchers). This operating system is based on Ubuntu (previously in Kurumin/Knoppix) and inspired
by Quantian Linux. It offers several specific tools in the areas of
GIS,
3D Visualization, Mathematics, Statistics, Genetics, Bio-Informatics and several other fields of research. It
also has all the software expected in a modern desktop such as a complete office suite - with spell checker, web browsers,
e-mail readers, instant messaging, to cite but a few. It is ideal for students, teachers, researchers, but also for any common (home) user. Please, see more here.

With Poseidon Linux 3.0 we started a new era for our project, since the new release is based on Ubuntu LTS (Long Term Support) it can be easily installed in Brazilian Portuguese, Spanish, English and German. The previous versions (1.3, 1.5, 2.0), based on Kurumin (a Brazilian Portuguese distro based on Knoppix), were Pt_Br, only.With Poseidon 3.1 we expanded the included languages to have also Greek, Italian and French. Another improvement is at the boot, because now the users are now able select their own languages right from the beginning when starting the live-DVD.Also, for Poseidon
Linux 3.1 we were pleased to announce -for the very first time- two
versions for 32 and 64 bits computers.

Last year our team was proud to announce the Poseidon Linux 3.2, born May/2010, and officially presented at the IV Brazilian Oceanography Congress!Due to software technical details (i.e.
some special packages included), only the 32 bits version was launched
then, based on Ubuntu 9.10. However it run in any kind of PC (with
"older" single-core processors, up to Dual, Quad, Intel_32 and AMD_64
processors).Version 4.0 was launched in 2010. Both 32 bits and 64 bits versions were released.This release is based on the Long Term Support (LTS) Ubuntu 10.04 (with 3 years of updates guaranteed by Canonical), since our goals are stability, usability and support for the whole system when used professionally at universities, institute, colleges and -also- at home.

Check out its looks:

Thenext version, Poseidon Linux 5.0 (in RC version, for now), will be the dawn of a new era for us. It will be based on Ubuntu LTS 12.04.1 and will have unity, as the default desktop environment. And based on the usage statistics and the users requests, we'll keep in the official ISO only the packages in use by our regular users. This version will be oriented to MBSystem, geostatistics and GIS, image management, office and multimedia, basically. The other packages (bio-informatics, etc.) can be installed by the users easily, later.

Poseidon
Linux is a GNU/Linux distribution. It was designed for the
academic and scientific community, following the need for a friendly,
complete and stable desktop based on open source, 100% free software. Our aim is not to deliver one new distro after another, but to deliver a solid, usable and trustful disto for professional and home computers, that will be updated when the special packages and the base system requires so.

It includes a large number of scientific applications, covering areas such as:

The new features in relation to our previous versions can be found in the changelog

The "special" version of Poseidon Linux designed to MB-System users can be found here (32bit) and here (64 bit)
